In an issue that could spur a health-care industry fight, a House select committee Monday will take up a 155-page bill that would give nurse practitioners independence to provide medical services without physician supervision. House leaders say giving more authority to nurse practitioners, at least in part, could help address a shortage of primary-care physicians in Florida. The bill would apply to a group technically known as "advanced registered nurse practitioners," who have more education and training than registered nurses. Along with applying to nurse practitioners who provide primary care, it would apply to specialists such as nurse anesthetists.
